Again, since I'm unfamiliar with Linux and Chromebooks, I don't think I'll be able to make a dedicated/compatible version for the foreseeable future ^^; I also don't want to combine the DLC with the base game and make it a standalone download, as that would be too many different versions of the base game + DLC for me to update and manage (in conjunction with the other versions for Windows, Mac, and possibly Android).
I'm very sorry to disappoint! But I appreciate your understanding nonetheless :3
